The K4 includes Digital Key 2 functionality that transforms compatible smartphones into secure vehicle keys. This system allows owners to lock, unlock, and start their vehicle without traditional key fobs.
Digital Key 2 Touch uses your smartphone like a secure access card. Owners can share digital key access with family members through the smartphone app, providing convenient access control for multiple drivers.
The system stores digital keys in Apple Wallet, Samsung Wallet, or Google Wallet depending on the smartphone platform. This integration provides security and convenience for daily vehicle access.

Climate Control Technology
Climate control systems range from basic air conditioning to advanced dual-zone automatic systems depending on the trim level selected.

Safety Technology Display:

The display systems use different colours and brightness levels to communicate the urgency of various alerts without overwhelming the driver with unnecessary information.

Interior Lighting and Ambiance
LED interior lighting provides clear visibility for controls and storage areas throughout the cabin. Higher trim levels include interior mood lighting that can be adjusted for different preferences.
